I'm pretty sure this is it, when jack FINALLY slips back into the Territories, He and Speedy talk. Speedy mentions the Gunslinger and says that he has made others, to which Sophia says that she hadn't thought it was possible. It's as much a ripoff as when we were told Jack Sawyer might appear in the DT books, which, by the way, he did. When Eddie is looking into the Rose in DTV he sees great things and near misses, dot dot dot, and he sees four men destroy a creature whose entire head appeared to be a huge eye. Love the books but the missed opportunities were glaring. BTW, at the end of DT4 King says endworld is a place for all of these characters to wash up, including Ralph Roberts. Was he referring to the book Insomnia because as far as I know the actual name 'Ralph Roberts' is never printed.
